What does the word 'insolent' mean in the context of behavior?

The term 'insolent' is used to describe a particular type of behavior characterized by a lack of respect or rudeness, often in a bold or arrogant way. When someone exhibits insolent behavior, they may openly disrespect authority or social conventions, showing a disregard for others' feelings or expectations. This aligns perfectly with the concept of being rude.

In contrast, the other options do not accurately capture the meaning of 'insolent'. 'Strange' conveys an idea of oddness or abnormality, 'fearful' suggests being afraid or anxious, and 'shy' indicates a reluctance to engage or interact due to nervousness. None of these terms connect to the notion of disrespectful or rude behavior that is encapsulated in the definition of 'insolent'. Therefore, 'rude' is indeed the most fitting interpretation of the word in the context given.
